Seaweed is lifted out of the top of an algae scrubber/cultivator, to be discarded or used as food, fertilizer, or skin care. Alginates are used in industrial products such as paper coatings, adhesives, dyes, gels, explosives and in processes such as paper sizing, textile printing, hydro-mulching and drilling.
Red algae, a (disputed) phylum contains about 7,000 recognised species, [50] mostly multicellular and including many notable seaweeds. [50] [51] Brown algae form a class containing about 2,000 recognised species, [52] mostly multicellular and including many seaweeds such as kelp. Unlike higher plants, algae lack roots, stems, or leaves.
Brown algae include a number of edible seaweeds. All brown algae contain alginic acid (alginate) in their cell walls, which is extracted commercially and used as an industrial thickening agent in food and for other uses. [54] One of these products is used in lithium-ion batteries. [55] Alginic acid is used as a stable component of a battery anode.
The benefits of seaweed and algae can also be seen in body products. “The St. Ives Sea Salt & Pacific Kelp Exfoliating Body Wash is a great plant based, hydrating wash particular for the winter ...
A giant "blob" of sargassum seaweed measuring 5,000 miles wide — twice the width of the continental United States — is headed for the Florida coast and already covering beaches with algae that ...
Macroalgae are the larger, multicellular and more visible types of algae, commonly called seaweeds. Seaweeds usually grow in shallow coastal waters where they are anchored to the seafloor by a holdfast. Like microalgae, macroalgae (seaweeds) can be regarded as marine protists since they are not true plants. But they are not microorganisms, so ...
The Fucales include some of the more common littoral seaweeds and the members of the order have the typical seaweed construction: a holdfast, stipe, and lamina. The lamina is often much branched and may include gas-filled bladders. Growth is by division of the apical cells.
Caulerpa taxifolia is a species of green seaweed, an alga of the genus Caulerpa, native to tropical waters of the Pacific Ocean, Indian Ocean, and Caribbean Sea. [2] The species name taxifolia arises from the resemblance of its leaf-like fronds [3] to those of the yew (Taxus).
